On October 22, 2008, the Seattle Mariners named Jack Zduriencik their newest General Manager. Assuming control of an organization that had been decimated by the foibles of its previous GM, Bill Bavasi, Zduriencik faced a daunting task in rebuilding the Mariners from the ground up.

Just 50 days after landing his new gig, Zduriencik made the first trade of his Mariners tenure. The deal was a blockbuster and would continue to have an impact on the ballclub five-and-a-half years later, where we find ourselves today.

Since that first trade in December of 2008, Zduriencik has proceeded to make 54 more trades for a total of 55 over five-plus seasons. The following is an analysis of all 55 of those transactions.

Trades are listed chronologically, from earliest to most recent. Players acquired in BOLD are current members of the Mariners organization. Grades associated with each trade are entirely subjective and reflective of the author’s opinion.
